关于Tomcat的URIEncoding以及GET乱码

评：


Service name="Catalina">
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" [b]URIEncoding="UTF-8"[/b] />

<Connector port="8099" protocol="AJP/1.3" redirectPort="8443" URIEncoding="UTF-8" />


而Linux 的配置缺少了URIEncoding的配置项，那么默认应该是"ISO8859-1",所以如果没有配置，则需要转码一次。

<!-- Linux 上Tomcat-->
<Service name="Catalina">
<Executor name="tomcatThreadPool" namePrefix="catalina-exec-" maxThreads="250" minSpareThreads="20"/>
<Connector port="80" protocol="HTTP/1.1"
connectionTimeout="20000" redirectPort="8443" compression="on" compressionMinSize="2048" noCompressionUserAgents="gozilla,traviata"
ompressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain,application/json,application/javascript,application/x-javascript"
/>
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" executor="tomcatThreadPool"/>


同理，如果在Linux上的Tomcat 加上URIEncoding="UTF-8" 就好了。

结论： 约定很重要，网站一般采用UTF-8作为默认编码。如果不是特殊需求，不要变换成其他编码。
